Video Transcript for Fulton Folding Tongue - Coupler Hinge Kit - FHDPW330300 Review

Speaker 1: Today we're going to take a look at the Fulton weld-on fold away coupler hinge kit for a three inch by three inch trailer tongue. Now this hinge kit will let you create up to a 48 inch fold away tongue for your trailer so that your trailer can be stored in even the smallest garage. It is designed to be used with actuators or standard couplers. It is a weld-on installation. It's a sturdy steel construction, has a nice raw finish to it. The pivot bolt and the pivot pinning clip are all included, and this is not for use on aluminum trailer frames.

It can be installed to swing in either direction. Basically what you can do is you can just pull your clip out here, pull your pin out. And then with that out, you can see how it will let you fold away your trailer tongue, and it can be installed to swing in either direction for your application.Now the application for this, again, is three inch by three inch trailer tongues. Now the trailer tongue material thickness must be between 3/16 of an inch and 1/8 of an inch. Capacity on this is up to 5000 pounds depending on the maximum pivot length, and there is a table on this product page that will show you at what pivot length the weight capacity will be.

And the total length on this is going to be right at 7-1/2 inches long. But again, you just take your pin, once you get it extended out, drop your pin through. Push your clip right through there. And then it's all locked in place and you're ready to go. But that should do it for the review on the Fulton weld-on fold away coupler hinge kit for three inch by three inch trailer tongues..

The trailer tongue hinge was as advertised and welded onto my boat trailer very easily. It has provided a means to have more space in my garage. I would highly recommend the great quality for anyone looking for a hinge on their trailer. 591137

Fantastic product. It made my boat trailor a lot smaller to get it in storage. Heavy duty item. Easy to work with. Had it welded on(smart move). Worth every cent. Great service, fair price, very happy! Will use them again for other trailor items 518084

Welded on clean. Seems quality. Definitely makes rattling noise going down the road. Might have to dampen with a thin piece of rubber between the two pieces that join. 498025

by:

I've had the folding tongue for a year now and appreciate it more every time I need to get into my limited storage space. I got the weld on unit and it was my first significant mig welder task. I had no trouble at all. It pivots smoothly into position when needed, then tucks back out of the way when I'm done. The only issue I had with it was figuring out the proper length of safety chain ) since it has to go behind the folding portion, and how best to attach the chain so it doesn't drag. A bit of trial and error solved that, though I wish this unit came with points of attachment for the chains 561517

by:

I selected the weld on application for its clean appearance. The added expense of using a certified welder for the installation was well worth it, I'm very satisfied with the product and it looks as if it was factory installed. Always a pleasure dealing with etrailer and your prompt service. 286500

The product worked very well for what I needed. I needed to lengthen the tongue of my trailer to get the boat deeper into the water when launching it but didn't want that to interfere with storing it in the garage. It was nice to have a chart that came along with it that gave length of tongue vs weight of boat so that you can more easily decide what length will work for your application. 564583

  • Option for Extending a 3 inch by 3 inch Trailer Tongue
    The only way I can recommend a tongue extender for your trailer that has a 3 inch by 3 inch channel is to remove your current coupler, install the hinge kit part # FHDPW330300 in place of it and then install your coupler onto a length of 3 by 3 channel, and then install this into the other end of the hinge kit. This will give you an extension for the tongue of your trailer and will allow you to fold the coupler back for an additional clearance if needed. Otherwise you would need...

  • How Do You Weld the Fulton Weld On Hinge Kit for 3x3 Tailer Frame and What Material is it Made Of
    The Weld-On Fulton Fold-Away Hinge Kit for 3" x 3" Trailer Tongue, item # FHDPW330300, is constructed of cast steel. All welding must be performed by a certified AWS welder. Making sure casting is straight and fully seated on the tongue tube. Weld complete on all four sides using a 3/16 inch minimum fillet weld.

  • Hinge Kit Recommendation for Trailer with Pole Tongue that Measures 2-1/2 inch Square
    What you would need is the # FHDPW330300. This is a hinge for a 3 by 3 inch trailer tongue. You'd need to have a welder put 1/4 inch spacers above and below the tube so that it fits yours that is only 2-1/2 inches tall.

  • Fold-Away Hinge Kit for a Trailer with 2 inch By 3 Inch Tongue
    We do have a fold away coupler that will work on your trailer tongue that is 2 inches by 3 inches and that is the Fulton # FHDPB230101. This coupler will install on your trailer tongue and has a cacity of up to 5,000 pounds. Please note that the tongue material thickness must be between 0.188 and 0.120 inches for installation purposes. The fold away coupler that you referenced # FHDPW330300 is intended for use on trailer tongues that are 3 inches by 3 inches and I would not recommend...

    For a 3 inch by 3 inch bolt on trailer tongue hinge kit you will need to use the Fulton Bolt On Fold-Away Coupler Hinge Kit, # FHDPB330301. This hinge kit is designed to bolt on without welding and allows you to create up to a 48 inch long foldaway tongue on your boat trailer, depending on the gross trailer weight and max tongue weight of the trailer. I added a chart that shows the GTW, TW and Maximum Pivot Length for the # FHDPB330301 fold-away. You should always install the fold -away...

  • Trailer Coupler Hinge Kit Recommendation for 3 inch by 3 inch Channel that is 1/4 inch Wall
    Since the channel of the tongue of your trailer is thicker than what the bolt-on kits recommend you would want to use the weld-on kit part # FHDPW330300 for your 3 x 3 inch trailer tongue to provide a hinge kit for it.

  • Can the Fulton Fold Away Coupler Be Installed In Either Direction
    I contacted the manufacturer of the Fulton Fold-Away Coupler, # FHDPW330300, and they told me that it does not matter which way you install the coupler to your trailer. You can decide which way you want you trailer coupler to swing that will work the best for your application.

    What you would need is the # FHDPW330300. This is a hinge for a 3 by 3 inch trailer tongue. You'd need to have a welder put 1/2 inch spacers above and below the tube so that it fits yours that is only 2 inches tall.

  • Can Pivot Bolt Be Removed from Fulton Fold-Away Coupler Hinge Kit FHDPW330300
    Yes, it is certainly possible to remove the pivot bolt from the Fulton Fold-Away Coupler Hinge Kit # FHDPW330300 to enable you to separate the two halves of the assembly. Both the pivot pin and pivot bolt are included with this assembly and it is intended for use on steel trailer frames (but not aluminum frames). Also note that the weight capacity will be a function of the pivot length. This is detailed in the chart on the page, which I have also linked for you.

  • Where Does the Trailer Jack Install on a Trailer if it has a Hinge Coupler
    You will want to put the trailer jack between the Fulton Fold-Away Coupler Hinge Kit # FHDPW330300 that you referenced and the frame of the trailer. If you had the jack on the side of the hinge that pivots it would make it unstable and difficult to pivot the tongue of the coupler. Not only would it make things much more difficult, but the hinge is designed to only support weight when it is locked out straight as both sides of hinge will have support to carry the weight. When the hinge...

  • Items Included in Fulton Fold-Away Coupler Hinge Kit FHDPW330300
    Fulton Fold-Away Coupler Hinge Kit # FHDPW330300 includes the two halves of the main coupler housing, mounting hardware and both a pivot bolt (and nut) and a pivot pin with handle and cotter pin. These items are shown in the linked photo. A center punch for dimpling the material prior to drilling is NOT included. Please note that this item's weight rating is dependent on the actual pivot length as noted in the linked chart. Capacity drops as pivot length increases.

  • How Much of Trailer Tongue Needs to Fit Inside Fulton Fold-Away Coupler Hinge Kit for 3 Inch Tongue
    The Fulton Fold-Away Coupler Hinge Kit # FHDPW330300 referenced in your question is compatible with 3 inch x 3 inch trailer tongues. The tongue on your trailer will just need to go in at least 3 inches on each side of the Hinge Kit. If you have this length available, this will work great to create up to a 48 inch foldaway trailer tongue. I have attached a short video demonstration on this product that you can also check out. For the brake lines and actuator on your trailer, it sounds...

  • Comparing Boat Trailer Surge Couplers with Manual and Electric Reverse Lockout
    Between a manual reverse lockout and an electric reverse lockout on your boat trailer brake actuator the electric option does avoid the need to get out of the vehicle each time you need to back up the trailer. An electric reverse lockout feature automatically disengages the surge coupler when you shift the vehicle into reverse; it does this by taking in the backup light signal from the vehicle and sending this to a solenoid that blocks the hydraulic fluid from reaching the disc brakes....

  • Availability of Fulton Hinge Kit to Fit Pole Tongue that is 2 inch by 3 inch
    The Fulton Hinge kit part # FHDPW330300 that you referenced is designed for a 3 inch by 3 inch pole tongue. If your tongue is 2 inch by 3 inch you'd just need to use 1/2 inch spacers on the sides of the tongue that are 3 inch and you'd be set. You'd want to have them welded on.

  • Fulton Fold Away Hinge Kit Recommendation for Trailer Tongue that is 2.75 by 2.75 inch
    The 3 inch by 3 inch hinge kit part # FHDPW330300 is the correct hinge you'll need, but since your trailer frame is a bit smaller than 3 inch you'll need to use spacers on the frame to take up the additional clearance so that it fits tightly.

  • Fold Away Trailer Tongue Hinge Compatibility with Coupler and Surge Brake Coupler
    Couplers are the foremost part of the trailer that attaches to the hitch ball. Actuators are trailer couplers that are normally on boats and have a surge brake system built in. Standard couplers are couplers without brakes. The Fulton Fold-Away Hinge Kit is the weld on version and there is a bolt on version available to create a foldaway tongue for a 3 inch by 3 inch trailer frame like # FHDPB330301 and # FHDPW330300. When determining the maximum pivot length make sure to use the table...

  • Are There Replacement Bushings for Fold-Away Coupler Hinge Kits
    I cannot speak for all fold-away coupler hinge kits but the ones we offer, the Fulton Fold-Away Coupler Hinge Kit part # FHDPB230101, part # FHDPB330301, and part # FHDPB350101 do not contain any bushings. It can be rather difficult to just look at a bolt or hinge pin and determine whether or not it has stretched or deformed but I would be willing to bet that is the issue you are having. The loose connection between these bolts and pins is a rather serious safety issue so I highly recommend...

  • Differences Between the Fulton Coupler Hinge Kits FHDPB330301 and FHDPB330303
    The difference between the two Fulton Swing Away kits you referenced is the material that is used for each of the kits. Other than that they are the same and are designed to fit 3 inch by 3 inch trailer tongues. The # FHDPB330301 is made of stainless steel which will resist corrosion and the part # FHDPW330300 is made of a raw steel which will corrode much easier. You could paint either kit if you like.

  • Availability of Folding 3 x 3-Inch Trailer Tongue Coupler for Aluminum Trailer
    We do offer a number of different fold-away couplers for various sizes of straight trailer tongues but these are intended only for use on steel trailer frames. Aluminum trailers, for all their good non-corrosive and lightweight nature, are simply not strong enough to allow the attachment of a hinged tongue mechanism like # FHDPB330301 and the others shown on the linked page. You can make absolutely sure by contacting Shorelander with your trailer's VIN number. As the maker of your trailer...

  • Should I Use a Bolt On or a Weld on Fold Away Coupler On a Shorelander Trailer with 3x3 Frame
    I more or less agree with you. The Fulton Fold-Away Hinge Kit for 3 x 3 inch Trailer Tongue - Weld-On, item # FHDPW330300, is a cleaner look and if you got a bad weld job you would not have a safe setup. I have done some welding, I am in no way a professional weldor, and in my limited experience a good weld will not fail before the steel it is welded to will fail. If you like the clean look of the weld on I would have a certified weldor perform the operation. If you take the trailer to...

  • How to Install Weld-On Folding Trailer Coupler on Trailer Frame
    The Fulton Fold-Away Coupler Hinge Kit # FHDPB330301 fits only a 3 x 3-inch trailer tongue. We do have other sizes of folding coupler, all are shown on the linked page, but none fits a 2-1/2- x 2-1/2-inch trailer tongue. To use one of these on your trailer you will need to use a 3 x 3 weld-on type coupler like # FHDPW330300 and have the qualified welder who will install it also install steel spacer plates on the trailer tongue before welding the coupler into place.

  • Weld-On Fold-Away Coupler Hinge for 3x3 Inch Trailer Tongue
    Technically you could weld on the bolt-on hinge # FHDPB330301, but instead, just use the weld-on version, # FHDPW330300. The bolt-on one is not meant to be welded on so the warranty would be voided if not installed the way it was intended. Plus the actual weld-on one costs less. The other issue is that the bolt-on version is zinc coated so that could cause some toxic gasses to be released when welding.

This is an unusual tongue size and we do not offer any folding couplers in this size.

    The Fulton Fold-Away Coupler Hinge Kit, Weld-On, part # FHDPW350300, is not for use on an aluminum frame trailer. It would need to be welded to a steel frame trailer. On an aluminum trailer you would need to check with the trailer manufacturer if a bolt-on hinge kit can be used. If it can, you can use the Fulton Fold-Away Coupler Hinge Kit, Bolt-On, part # FHDPB350101. This will fit the 3 inch x 5 inch tongue you have referenced.

    The Fulton Fold-Away Coupler Hinge Kit # FHDPB330301 referenced in your question does limit the trailer tongue thickness to between .188 and .120 inches for it to be compatible. This is simply because the Torx bolts that are included in the kit are a certain length and the nuts may not catch the threads when installing the kit onto a thicker tongue. We have checked with Fulton and they stated that you can replace the fasteners with a grade 5 fastener if you choose to use it on a 1/4 inch...

  • What Kind of Welding Is Required to Install Fold-Away Coupler Hinge Kit FHDPW230300
    Wire feed welding would be the best welding method to secure the # FHDPW230300 hinge kit to your existing trailer tongue. To install the hinge, you would simply cut the tongue at the point at which you want it to pivot, and then slide the two sides of the hinges over the newly cut ends. They will slide on about 3 inches on each side. To determine the maximum pivot length for your particular trailer, I recommend taking a look at the chart on the product page for hinge kit # FHDPW330300. The...

  • Installation and Quality Details of the Fulton Fold-Away Coupler Hinge Kit, # FHDPB330301
    When the Fulton Fold-Away Coupler Hinge Kit, # FHDPB330301, is in the closed position, it measures 7-1/2 inches long. Each end of the trailer tongue will go in at least 3 inches and is held in place by 4 bolts a piece. When properly installed, the hinge will not degrade the integrity of the trailer or lower its capacity. If you stay within the capacity and do not overload the trailer you should not have bending or cracking problems. If the pivot length is at the maximum of 34 inches,...
